Preface

The operating system “CentOS 7” has reached its end of life. For this reason Lise’s CPU partition will be updated to “Rocky Linux 9”. This affects all login and compute nodes equipped with Intel Xeon Cascade Lake processors ("clx" for short). Lise's GPU-A100 partition and GPU-PVC partition are not affected.

titleI have loaded the "intel/2024.2" environment module, but still neither the icc nor the icpc compiler is found. Why that?

Starting with the 2022.2 release of Intel’s oneapi toolkits, the icc and icpc “classic” compilers (C/C++) have been marked as “deprecated”, see here. Corresponding user warnings

icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is deprecated and will be removed from product release in the second half of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended compiler moving forward. Please transition to use this compiler. Use '-diag-disable=10441' to disable this message.

were generated when using icc or icpc. Intel’s oneapi toolkits version The 2024.x releases of the Intel oneapi toolkits do not contain icc and icpc any longer. Users need to switch to Intel’s “next generation” icx and icpx compilers, respectively. They accept almost all of the “classic compiler” switches. More information is available from Intel’s porting guide.
